The task of installing the waterwheel was naturally to start with a larger one and then a smaller one. The large bluestones that fixed the waterwheel support had already been placed in the pit at the bottom of the slope. Hua Xi first asked dozens of strong and powerful tribesmen to work together to place a large wooden stake in the pit.
Inside the circular hole of the big bluestone, it erected diagonally toward the middle of the eight big bluestones.
The bluestone is large and heavy enough to support the large wooden pile supports tens of meters high. After most of the day's work, when the sun went down, the eight waterwheel supports were installed.
Seeing that it was already getting late, Hua Xi stood on the high slope and shouted to the tribesmen below the low-lying land: "Okay, let's do it here first. Tomorrow, everyone will work harder and strive to get the water within one day."
The car is set up”
"Here!" everyone shouted in unison
Early the next morning, when there were still layers of white cold mist in the sky, the site of the workshop was crowded with people. Many tribesmen who heard the news gathered around the eight waterwheels that were higher than the city wall.
From time to time, there were noisy discussions among the crowd around the support. From time to time, some tribesmen pointed at the behemoth in front of them, saying something. Needless to say, the myth about the tribe leader must have been promoted by the people of the North tribe in the past few days.
Opened
Hua Xi calmed down and cleared away his distracting thoughts. Now it was time to install the waterwheel.
Following yesterday's work, Hua Xi personally went into battle. With the help of dozens of tribesmen, the dozens of bearings that fixed the bracket, the gears and small brackets that helped the wheels rotate, and the blades that blocked the water flow were all completed in four or five hours (one day).
After a busy and tense and orderly struggle (time = 2 hours), the installation of the waterwheel was announced to be completed.
The ditch, which was seven to eight meters wide, had already been dug. After Hua Xi gave an order, the tribesmen opened the three-meter earth wall that blocked the ditch and the flow of the Bailong River. The surging Bailong River water rushed in, and the water flowed along the ditch.
It has been flowing rapidly for hundreds of meters, and when it reaches the high slope, it rushes down with a thunderous impact. With the continuous replenishment of the water, it continuously impacts the blades of the waterwheel with unparalleled horsepower. The waterwheel is impacted by the water energy.
Next, a harsh squeaking sound was heard, and the friction between the water wheel bearing and the wooden stick made a loud roar. Hundreds of tribesmen suddenly discovered that the behemoth turned on its own without any human contact.
stood up, there was an uproar in the crowd, screaming
The waterwheel rotates slowly at first. Under the constant external force, the waterwheel gradually speeds up, and finally maintains a slow but stable rotation at a constant speed. The large bearing part is wrapped in bronze skin, so the sound it makes is a bit muffled.
"Oh...success!"
"Ha ha……"
The crowd burst into thunderous applause and cheers again
Looking at the continuously rolling waterwheel, Hua Xi suddenly noticed a trace of white smoke floating between the bearings of the waterwheel. Hua Xi shouted: "Oops!" and immediately ordered Mulu to remove the leaves from the waterwheel.
When everyone was puzzled, the waterwheel stopped spinning after losing its blades. Hua Xi asked Muru to make four or five more small wooden barrels, and then used a bronze ax to carve out several small wooden barrels on the wooden wheel of the waterwheel.
Inlaid grooves to install the barrel
The blades were loaded again, and the waterwheel continued to rotate very quickly. The large wheels of the waterwheel turned squeakingly. Several small wooden barrels mounted on the wooden wheels turned to the ground under the rotation of the wooden wheels.
The bottom barrel sinks into the water, and a bucket of water rises up. When the barrel rolls to the top with the wheel, the clear water in the barrel pours down under the effect of the gravity of the earth, and is sprinkled on the bearings connected.
In this way, the problem of bearing heating is solved.
On the bearing of the wheel, there is a large wooden stick that Hua Xi has nailed to it with bronze nails. As the wheel rotates at a constant speed, the wooden stick also moves in a circle according to the trajectory of the wheel. The other side of the wooden stick
One end is in a pit not far from the waterwheel, stirring the river water flowing in.
Hua Xi poured some weeds, wood chips, bamboo fragments and other things that had been processed by the tribe into a pool of papermaking raw materials. It had no effect on the stirring of the wooden stick. The wooden stick continued to stir back and forth at the original speed as before.
With
The wood pulp tank is very large, about seven or eight square meters in size. In order to speed up the process, Hua Xi added lime and other alkaline substances into the wood pulp tank to soak and cook the materials. This greatly improved the efficiency of paper production.
Lime naturally reacts. The process of cooking materials takes some time to soak the solid materials until they are soft, and stirring and melting Hua Xi is not enough. It is just a good time to adjust and optimize some of the links in the middle.
Seven days later, the originally hard wood became soft due to the long-term cooking and corrosion of lime. Under the stirring of the wooden stick, it turned into a yellow-white liquid. After passing through a filter made of bronze, it flowed into the
In a slurry tank at the back
As the liquid in the wood pulp tank gradually changed from yellow-white to ru-white, Hua Xi, who was making paper for the first time, estimated that those ru-white wild vines were the finished material for making paper.
Hua Xi ordered someone to use a ladle to pour out a few ladles of mud-like wood pulp from the pulp tank, and then put it into another small pond. Pour in a small amount of water to dilute the small pond. Hua Xi named it the paper trough. When the trough was ready, Hua Xi
After carefully filtering the pulp with another tribesman using a thin bamboo curtain, the bamboo curtain from which the pulp was collected was spread flat on a wooden board. After the bamboo curtain was removed, a thin layer of white thick pulp fell on it.
on the wooden board
The following are the two important processes of paper manufacturing, removing moisture and baking to remove moisture. Hua Xi has already prepared. That is to take a flat bluestone slab, gently press it on the paper pulp, and then shout the slogan,
When he and several tribesmen pressed the bluestone board down hard, the moisture in the pulp flowed out along the edge of the board. Under the pressure of the heavy object, the paper film slowly formed, turning into a square piece of paper.
Looking at the first piece of paper in the primitive era, Hua Xi smiled. When the others saw the patriarch showing a happy smile, they didn't know why they laughed, but the happy atmosphere still infected everyone. So, everyone's face
There is a silly smile on the face
The last process is to bake the paper. It can be dried directly in the sun or air-dried. You can also build two brick walls. When baking the paper, first light a fire in the tunnel, and then use light copper tweezers to separate the sheets one by one.
The wet paper is spread on the wall, and the heat radiated from the gaps slowly dries the paper. When it is dry, it is lifted up and becomes a usable piece of paper.
However, Hua Xi thought of a way to improve efficiency, which is to overlap dozens of wooden boards for storing pulp at a time, and then use bluestone to remove the water in one row. This way, the efficiency is much faster than before.
When the first piece of paper was completely seated, a slightly yellowish white paper appeared in front of everyone. It felt very delicate and gentle in the hand. Hua Xi raised the paper in his hand and shouted: "Paper!"
"Paper!" the crowd of onlookers shouted.
When Hua Xi took a charcoal pen and wrote the word "中华" on the white paper, people let out a cry, as if they understood the use of this item called "paper"
Hua Xi put the paper into Hua An's hand again, and then let the paper run around in the crowd before returning to his hand, and shouted loudly: "I know what the advantages of using paper to record things are compared to those animal skins.
No?"
"Clear..."
“Easy to carry!”
"fine!"

It’s good that people have mentioned the benefits one by one. The minds of barbarians are as smart as ours. When they discover new things, they can quickly explore different functions from them.
